Global Warming
Since human antiquity
until today, humans have always been progressing in every period of time
passed. Current human civilization has been a lot of progress. During
development, the human living and being dependent on farming and agriculture.
Through the life orientation, people are always trying to maintain and preserve
the environment as well as possible which aims to sustain human life. Humans
have now experienced the industrial revolution which lives depend on the
industry sector. By using the life orientation, world agriculture was declining
gradually.
The values of human
life underwent a change, especially in human interaction with the environment.
The changes that occurred this produces a positive or negative impact. One of
the effects of the industrial revolution that has occurred and is continuing on
the present in the life and human civilization is its impact on the environment
that exists around the man himself. Expansion efforts by industry players such
as the construction of factories and manufacturing production with a large
capacity to the exclusion of attention to its impact on the environment is
slowly but surely have resulted in the negligence that will ultimately harm the
living environment and human life. Environmental experts have found indications
of the impact on the environment and the world's most globally due to efforts
made and the industry has been growing rapidly at this time.
This negative impact is
the warming in the world and is often referred to as global warming. However,
the problem of global warming as an environmental issue is still debated truth
by some parties. The party considers global warming is the reason that was
created to limit the pace of industrial development. Although there is still a
debate about the truth of the state of global warming among environmental
experts, the problem is not global warming can diungkiri to be researched and
investigated further for the survival of human life.
Global warming is often
diperbincangakan today and has become a common issue in many parts of the
world. Many people are already familiar with the global warming that is bad for
life, either for humans, plants and animals and the natural surroundings.
Understanding global warming which many experts defined processes, the causes,
effects and ways to overcome is the most important thing in the study about
global warming. In simple terms the meaning of global warming is the increase
in average temperature well above the Earth's surface on land, sea or in the
air so that the temperature of the earth is getting longer be hotter. And in
general, is an event of global warming increasing the average temperature in
the layer of the atmosphere and Earth's surface.
We
all know the impact is very harmful to the health of our planet and of course
has implications for all the inhabitants of the earth. According to various
studies, at this moment in Earth's surface temperature has shown a drastic
increase of around 0.6 ° C, which occurred in the last century. Improvement and
looks fairly small, but the impact of global warming are very big for the earth
and life on earth. In symptoms or signs of global warming we can observe and
feel. One of the symptoms of global warming that we now feel is the turn of a
difficult season we predicted, the frequent occurrence of a tornado, bleached
reefs, and floods and droughts in the region of an unusual experience.
Causes
of Global Warming
Many
experts who express an opinion about the causes or factors of global warming.
According to the experts that the Earth's surface warming due to increased
greenhouse gases in the atmosphere that trap heat, not only that, there are
many more causes of global warming need to be friends to know in repair and
overcome it. Global warming happens for a reason, as for some reason, among
others:
- Greenhouse Effect
All
energy sources that exist on Earth comes from the sun. Most of the energy in
the form of short-wave radiation, including visible light. When this energy
arrives surface of the Earth, he turned on the light into heat that warms the
Earth. Earth's surface will absorb some of the heat and reflect the rest. Some
of this heat tangible long-wave infrared radiation into space. However, some
heat remains trapped in the earth's atmosphere due to the accumulated amount of
greenhouse gases that become traps for this radiation. These gases absorb and
reflect radiation emitted by the Earth and consequently the heat stored in the
Earth's surface. This situation occurs continuously, resulting in an annual
average temperature of the earth continues to increase.
- Feedback Effects
The
causes of global warming are also influenced by various feedback processes that
result. An example is the evaporation of water. In the case of warming caused
by greenhouse gases such as CO2, warming will initially cause greater volumes
of water that evaporates into the atmosphere. Because water vapor is itself a
greenhouse gas, warming will continue and increase the amount of water vapor in
the air until it reaches equilibrium with the water vapor concentration. The
resulting greenhouse effect greater than the effect of CO2 alone. This feedback
affects only slowly because of CO2 have longevity in the atmosphere.
- Electricity Wastage
Electricity
is used by everyone, but many people are not aware of the savings on
electricity usage. Various appeals have been widely driven or carried out, but
in reality many people can not do, so the waste of this electricity could be
one contributor to the increasing global warming.
- Fuel
Fuel
used vehicles in addition to harm the health also gives the effect of the
increase in global warming of the air pollution produced by each vehicle.
- Air Pollution From Industrial And Factory
More
and more industries and plant-growing, more and more global warming. Indeed the
plus side, industry and factory can provide opportunities for the welfare of
the people, but on the other hand smoke damages resulting from the industry and
very detrimental to acknowlege earth plant.
- Barren forest
Many
forest fires occurred illegally without permission from the government. In
fact, many forest functions, one of which is to prevent flooding. Additionally,
hutanpun can reduce heat in the earth's temperature is increasing. A source
said that global warming increases by 50% the cause is CO2, or carbon dioxide.
So deforestation has led to the increase in global warming of the earth.
Impact
of Global Warming
Many
very adverse impact generated and perceived by all living creatures on earth
because of the golbal warming is increasingly rising. As for the impacts to the
lives of, among others:
- The longer the temperature of the earth's surface will be more extreme
- Sea levels worldwide would rise
- The intensity of hurricanes will increase
- Many droughts and crop failures worldwide
- There will be famine and drought earth
- Various diseases emerging due to global warming
- The extinction of some species of living creatures
- Icebergs will melt
- Rainfall will increase and storms will often occur
- Ground water will evaporate quickly cause drought
How
to Prevent Global Warming
Some
ways to reduce, prevent, cope with and overcome the effects of global warming
are as follows:
- Changing Personal Conduct
Better
action in addressing, reducing, and prevention of global warming is to change
human behavior, because an understanding of global warming invested today will
have a major impact on future generations. Here are some examples of personal
behavior that can be done to reduce, prevent, and address global warming, among
others, as follows :
- Saving Electricity
- Plant Trees
- Reducing the Use of Automobiles
- Steps to Prevent Global Warming Collective
Global
warming prevention efforts can also be done jointly or collectively. Several
steps can be taken collectively are as follows:
- Using Alternative Energy
- Preserving Forests
- Remove the use of CFC
- Improve the quality of vehicle emission test
- Reducing Carbon
- To reduce the CO2 gas in the air can be done with the following things
- Planting and maintaining plants in large numbers
- Replacing the use of fossil fuels with alternative fuels, such as water, wind, and sunlight
